FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The pixels, or color samples, that form a digitized image (such as a JPEG file used on a web page) may or may not be in one-to-one correspondence with screen pixels, depending on how a computer displays an image. In computing, an image composed of pixels is known as a bitmapped image or a raster image.

Detailed explanation-2: -A bitmap (also called “raster") graphic is created from rows of different colored pixels that together form an image. In their simplest form, bitmaps have only two colors, with each pixel being either black or white.

Detailed explanation-3: -raster graphics, also called bitmap graphics, a type of digital image that uses tiny rectangular pixels, or picture elements, arranged in a grid formation to represent an image.

Detailed explanation-4: -The difference between the two image types is that while bitmap images are made up of pixels, vector files are made up of lines described by equations. This means that as you zoom in on a bitmap image it will become “grainy” while a vector file will stay smooth and sharp.

Detailed explanation-5: -Raster Images These are the types of images that are produced when scanning or photographing an object. Raster images are compiled using pixels, or tiny dots, containing unique color and tonal information that come together to create the image. Since raster images are pixel based, they are resolution dependent.
